Iron ore mining methods vary by the type of ore being mined. Currently, there are four main types of iron ore deposits, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite, and piso-litic ironstone deposits. For taconite iron ores, mining iron ore begins at ground level.

With dry processing, the entire stone, including the impurities, is ground into product. Wet processing, in contrast, offers the opportunity to improve the purity of the products by a reverse froth flotation process. The reverse flotation process removes the impurities, usually highly colored, from the carbonate ore as a froth.
